SecureRF announced the availability of the LIME Tag NX01, a secure NFC tag that utilises Public Key Infrastructure (PKI) technology to deliver identification and authentication solutions that require no database or Internet connectivity when performing an authentication. The ‘passive’ NX01 does not require a battery or other external power source and is available as an inlay, card, or chip for integration into existing products, labels or tags. The PKI security features address a wide range of commercial applications including credentials, product and brand protection, ticketing, and other high value transactions. The LIME Tag NX01 provides a dual interface option for both contact and contactless deployment. Both interfaces, ISO7816 and ISO14443, are supported when using the contact power mode. The NX01 can be used as a contactless card or tag too. In contactless mode, the NX01 can be used with most NFC-enabled smartphones or readers and is supported by SecureRF’s Veridify Smartphone App, which in addition to authentication, can provide visual verification, location, and messaging features. The LIME Tag NX01 is suitable for credentials and authentication solutions including item-level brand protection and anti-counterfeiting for pharmaceutical, spirits, electronics and fashion products.
